Narrow bezel liquid crystal display module

Abstract

A narrow bezel LCD module, comprising: a liquid crystal panel; a backlight module having at least one plastic frame to carry the liquid crystal panel; a front frame surrounding the plastic frame to fix the liquid crystal panel and form an accommodating space formed between the front frame and the plastic frame; at least one flexible package component disposed in the accommodating space and having a flexible circuit board which electrically connects to the liquid crystal panel and a driver circuit board; and at least one guide block disposed in the accommodating space, fixed on one inner side of the front frame and having a guide slope facing the flexible circuit board. The invention can avoid the flexible package component from being curved upward and damaged.

What is claimed is: 
     
       1. A narrow bezel liquid crystal display (LCD) module, comprising:
 a liquid crystal panel having an upper glass substrate and a lower glass substrate; 
 a backlight module having at least one optic film, a back plate and at least one plastic frame, wherein the back plate carries the optic film and the plastic frame surrounds the back plate to carry the liquid crystal panel; 
 a front frame surrounding the plastic frame to fix the liquid crystal panel, and an accommodating space formed between the front frame and the plastic frame; 
 at least one chip-on-film (COF) flexible package component disposed in the accommodating space and having at least one chip and a flexible circuit board, wherein the chip is fixed on one surface of the flexible circuit board facing the plastic frame, one end of the flexible circuit board electrically connects to the lower glass substrate and the other end of the flexible circuit board electrically connects to a driver circuit board; and 
 at least one guide block, which is a conductive foam block, wherein the guide block is disposed in the accommodating space and fixed on one inner side of the front frame and tightly adhered to the inner side of the front frame by a double-sided adhesive tape, and the guide block has a guide slope facing the flexible circuit board; 
 wherein the guide block, which is a strip having triangular or trapezoidal cross-section, is adhered to the inner side of a corner position of the front frame and extends over a corner of the front frame. 
 
     
     
       2. The narrow bezel LCD module according to  claim 1 , wherein the guide slope of the guide block and the flexible circuit board has a gap formed therebetween. 
     
     
       3. The narrow bezel LCD module according to  claim 1 , wherein the guide slope of the guide block is in contact with the flexible circuit board. 
     
     
       4. A narrow bezel liquid crystal display (LCD) module, comprising:
 a liquid crystal panel having an upper glass substrate and a lower glass substrate; 
 a backlight module having at least one optic film, a back plate and at least one plastic frame, wherein the back plate carries the optic film and the plastic frame surrounds the back plate to carry the liquid crystal panel; 
 a front frame surrounding the plastic frame to fix the liquid crystal panel, and an accommodating space formed between the front frame and the plastic frame; 
 at least one flexible package component disposed in the accommodating space and having at least one chip and a flexible circuit board, wherein the chip is fixed on one surface of the flexible circuit board facing the plastic frame, and one end of the flexible circuit board electrically connects to the lower glass substrate and the other end of the flexible circuit board electrically connects to a driver circuit board; and 
 at least one guide block disposed in the accommodating space and fixed on one inner side of the front frame, wherein the guide block has a guide slope facing the flexible circuit board; 
 wherein the guide block is adhered to the inner side of a corner position of the front frame and extends over a corner of the front frame. 
 
     
     
       5. The narrow bezel LCD module according to  claim 4 , wherein the guide block is a foam block. 
     
     
       6. The narrow bezel LCD module according to  claim 5 , wherein the guide block is a conductive foam block. 
     
     
       7. The narrow bezel LCD module according to  claim 4 , wherein the guide block is a silicone block. 
     
     
       8. The narrow bezel LCD module according to  claim 7 , wherein the hardness of the silicone block is less than 30 degrees. 
     
     
       9. The narrow bezel LCD module according to  claim 4 , wherein the guide slope of the guide block and the flexible circuit board has a gap therebetween. 
     
     
       10. The narrow bezel LCD module according to  claim 4 , wherein the guide slope of the guide block is in contact with the flexible circuit board. 
     
     
       11. The narrow bezel LCD module according to  claim 4 , wherein the guide block is tightly adhered to the inner side of the front frame by a double-sided adhesive tape. 
     
     
       12. The narrow bezel LCD module according to  claim 4 , wherein the guide block is a strip having triangular or trapezoidal section. 
     
     
       13. The narrow bezel LCD module according to  claim 4 , wherein the flexible package component is a chip-on-film (COF) flexible package component or a chip-on-glass (COG) flexible package component.
